Miniature rose variety ‘POULgo003’

ABSTRACT

A new miniature rose plant which has abundant, coral-pink flowers and attractive foliage. This new and distinct variety has shown to be uniform and stable in the resulting generations from asexual propagation.

SUMMARY OF THE INVENTION

Classification:

Botanical.—Rosa hybrida ‘POULgo003’.

Commercial.—Miniature.

The present invention constitutes a new and distinct variety ofminiature rose plant which originated from a controlled crossing betweenan unnamed and unpatented variety, and ‘POULrijk’, described andillustrated in U.S. Plant Patent application Ser. No. 09/261,445, datedMar. 3, 1999. The two parents were crossed during the summer of 1994 andthe resulting seeds were planted in a controlled environment inFredensborg, Denmark. The new variety is named ‘POULgo003’.

The new variety may be distinguished from its seed parent, an unnamedseedling, by the following combination of characteristics:

1. ‘POULgo003’ has coral-pink flowers, whereas the seed parent has pinkflowers.

2. ‘POULgo003’ exhibits pendulant to procumbent growth, while the seedparent has compact, upright growth.

The new rose may be distinguished from its pollen parent, ‘POULrijk’, bythe following combination of characteristics:

1. ‘POULrijk’ is a ground cover shrub rose, whereas ‘POULgo003’ is aminiature rose.

2. ‘POULrijk’ has a spreading habit while ‘POULgo003’ exhibits aprocumbent habit.

3. ‘POULrijk’ has semi-double, pure pink flowers, while ‘POULgo003’ hasdouble, coral-pink flowers.

The objective of the hybridization of this rose variety was to create anew and distinct variety for garden use with unique qualities, such as:

1. Uniform and abundant flowers;

2. Vigorous, but compact growth when propagated by cuttings;

3. Disease resistance;

4. A miniature rose suitable for use in hanging basket containers in thenursery industry.

This combination of qualities is not present in previously availablecommercial cultivars of this type and distinguish ‘POULgo003’ from allother varieties of which we are aware.

As part of their rose development program, L. Pernille Olesen and MogensN. Olesen germinated the seeds from the aforementioned hybridizationduring winter of 1994 and conducted evaluations on the resultingseedlings in a controlled environment in Fredensborg, Denmark.

‘POULgo003’ was selected in the spring of 1995 by the inventors as asingle plant from the progeny of the aforementioned hybridization.

Asexual reproduction of ‘POULgo003’ by traditional budding and rootedcuttings was first done by L. Pernille and Mogens N. Olesen in theirnursery in Fredensborg, Denmark in July 1995. This initial and othersubsequent asexual propagations conducted in controlled environmentshave demonstrated that the characteristics of ‘POULgo003’ are true totype and are transmitted from one generation to the next.

BRIEF DESCRIPTION OF THE DRAWING

The accompanying color illustration shows as true as is reasonablypossible to obtain in color photographs of this type the variety rose‘POULgo003’.

Specifically illustrated in SHEET 1 is a plant of ‘POULgo003’ growing ina 20-cm hanging basket.

DETAILED DESCRIPTION OF THE VARIETY

The following is a description of ‘POULgo003’, as observed in its growthin Jackson County, Oreg., on plants aged 18 months. Color references aremade using The Royal Horticultural Society (London, England) ColourChart, 1995, except where common terms of color are used.

For a comparison, several physical characteristics of the rose variety‘POULria’, a rose variety from the same inventors described andillustrated in U.S. Plant Patent application Ser. No. 09/274,686 anddated Mar. 24, 1999 are compared to ‘POULgo003’ in Chart 1.
